[2025-09-30T08:29:03.039018] [PI reasoning] **Determining Piaget's stages**

I'm considering Piaget's preoperational stage, which spans from ages 2 to 7 years. The best option here is C, which lists it as '2-6 years,' though it's typically understood as 2-7. The other age ranges pertain to different stages: '7-12 years' is concrete operational, and '12 years onwards' is formal operational. I could search for more details about Piaget's theory to back this up.
